Ok, thank you.
The units in both option 7 of topology analysis module and the unit in color-filled map are a.u.
It seems that you identified an incorrect CP.
I have reproduce your AIM analysis, as can be seen from the following map, the BCP between N86 and Ni121 is 390
I checked its density, the value is 0.06968 a.u.
Then I plotted electron density map for the plane defined by atoms 121, 86, 102:
As indicated by the arrow, the BCP between N86 and Ni121 indeed has electron density of about 0.06968 a.u.
Well, I check the CP number before making the comparison.
Also, after re-running all the calculations now, the CP number changes, but again, the values are different in the graph from the exported data.
Could you, check this for me, please? Could it be a issue with units? A difference between the units on the exported file and in the graph?
Thanks in advance.
The CP389 is not between Ni121 and N86, but between N75 and H141, see below map
Note that I just updated Multiwfn on the website, new improvement:
In the GUI of topology analysis module, a new option has been added to menu: "CP labelling settings" - "Labelling only one CP". After choosing it and input a CP index, e.g. 19, then only label of CP 19 could be shown when "CP labels" check box has been selected. This improvement makes finding a specific CP from topology map much easier for large systems.
Thank you.
I already sent the email.
Please send your wavefunction file to my E-mail, I will check
Hello,
I did the critical point analysis, exported the file with all the data and also made the plots for the electronic density, its Laplacian, the ELF and LOL index.
When comparing the obtained data for bond critical points, between the text file and graph, they don't correspond, i.e. the value are different from the scale.
For example, from the calculation, the electronic density at the BCP389 (between Ni121 and N86) is 0.3246659890E+00. From the graph, the color should be cyan but it is blue (indicating lower density).
I checked the BCP number with the 3D plot with labels.
The same applies to ELF and LOL.
